New Client Announcement

Onesto, one of Belgium's leading social mortgage and renovation lenders, has deployed Herman to transform how its team processes loan applications. With a mission centered on long-term, affordable homeownership for families, Onesto needed a solution that could handle the administrative complexity of mortgage processing - without losing the human attention each applicant deserves.

Herman now automates document validation, data extraction, fact-checking, and credit policy checks across Onesto's mortgage applications. The result: analysts spend less time navigating paperwork and more time understanding the person behind each file - assessing financial resilience and connecting borrowers to renovation advice through Onesto's One-Stop Shop model.

"At Onesto, our mission goes beyond granting loans. We aim to ensure that families can not only buy a home, but continue to live in it affordably in the long term. By integrating AI into our document analysis process, we free up valuable time for our experts to focus on each applicant's specific situation. Herman supports our team in handling administrative complexity, so we can invest more attention in responsible lending and in connecting borrowers to renovation advice through our One-Stop Shop model." - Hans Vermeulen, CEO, Onesto.

"Herman automates the full mortgage underwriting workflow - document validation, data extraction, fact-checking, policy application - in minutes rather than hours. What makes Onesto's case particularly compelling is the complexity involved: renovation financing, many document types, and detailed policy requirements that would typically demand significant analyst time on every single file. Onesto is a strong example of what responsible AI adoption in lending looks like in practice.” - Geert Van Kerckhoven, CEO Oper Credits.
